Vernier Caliper Measuring Tool 6", 0-6Inch/0-150mm Manual Non Digital Calipers, 0.001"/0.02mm High Precision Durable Micrometer

I find great value in this tool. With proper care, it should last a lifetime. I do not know why Amazon desires that I mention Battery Life; but I will say this model was specifically selected because it requires no battery, has no electronic display or any digital functionality (to fail or go out of Calibration). Best described as, "Analog baby." Accuracy confirmed against a different, trusted, 0.001 Caliper and this thing is closer than the listed specifications give it credit for. If for some reason you cannot read a labeled slide-rule, this probably won't work for you. For everyone else, this is the simple, accurate, functional Caliper that you are looking for. I will leave it to a hand model to demonstrate that the thumbscrew locking operation is excellent and smooth, it has smooth and stiff slide-action (not sloppy at all), nice probe depth and allows grip and control in use. Case and even a cleaning cloth included.

Nice tool. Vernier are not exactly in vogue, but this is very handy in most application. It reads well and moves well. Of course it is not a Starrett or Mitutoyo, but it isn't prices as those and other brands. Buy it for what it is and you will probably be happy with it.

Bought this for rough use in nasty conditions where absolute accuracy isn't important. The calipers are rough but accuracy is good enough. Decided to smooth out some of the burrs and interference with a bit of 1000 grit paper. After a half hour of light polishing they run a lot better.

I was drawn to this particular caliper because: * it requires no battery * convenient size * all metal construction * budget friendly Fully satisfied with all of the above. As others have noted the finish is not highly refined- but neither is the price point so that’s not a big deal to me. It’s perfect for my needs which are hobby and homemade projects.

Most of the other reviewers complains about various issues with this caliper: accuracy, oily, possibility of rust, roughness of edges. All right complains, but they need to be put in perspective. If you are considering the purchase of a vernier caliper you know at least something about mechanics. How many parts made such a device? Building that many, with highest quality material, to the highest possible standard for accuracy (hence sharp) on one side of the part (the "internal") and for user friendly (hence smooth) on the other side (the "external") cannot be made cheap. All manufacturing procedures have tradeoffs. So for the price, this is an excellent product. Is it accurate enough? Yes, mine is accurate to the level of the vernier scale, however a tiny bit wobbly at that level, hence one less star in accuracy. Easier to read. Is it oily? Yes, but for most use that's minor problem. Is it rusty? No, but the manual says that if you clean the oil completely it might become so. Is it smooth? No, it's a bit sharp. If I had time to spare and would use it more often than I do, I'd try to smooth it with a file. But for occasional use it's totally usable. At this price, it totally deserves five stars. Granted, if you compare it with a similar one costing 10x its price, it would barely get two stars, perhaps it'd get even just one. But that would be an unfair comparison, like a race between an accomplished world champion and a random kid in middle school.

Quality seems excellent. My HF digital caliper also claims 001" precision and also shows the next half-thousandth (.0005"). It matched this vernier caliper, nearly always to the half-thousandth. And two other inexpensive calipers matched this vernier caliper. The one I received seems to be built correctly in contrast to some other reviews. However - I thought I could read Vernier, I learned on pre-electronics land survey instruments long ago. But the graduations on the Inch scale are so close that I mis-interpreted the reading, about one-third of the time. And note you will need a magnifier - I use a jeweler's headband stereo magnifier - to see the reading. I would write down what I thought was the measurement. Then the digital caliper, about a third of the time, would show at least .010" larger. Back to this vernier caliper, I found a matching tic at that larger measurement that also was as perfect a match as what I had relied on. One workaround for this mis-reading is to look at the measurement on the coarse scale and estimate between the tics, for example 60% of the way to the next tic. Then go look for a perfect match on the fine scale. In the example of 60% that will be about +.014". (60% x .025" graduations). This thing is definitely Old School. No battery needed, which is why I bought it. But the need to use a magnifier to read it makes it less convenient than the modern digital one. I watched a YT video explaining a Starret (famous quality brand) vernier caliper and I see the Starret is easier to interpret. Its coarse graduations are .050" while this one has .025". And its fine scale is twice as long with larger graduations, so its easier to see where tics match. With good eyesight a magnifier wouldn't be needed. The ultra-small graduations are not only hard to read. Coarse graduations of .025" plus adding a number 0~25 from the fine scale to arrive at total measurement is more confusing than I expected and prone to error. The Starret, for inches, and the mm scale on this, are easier math to work in your head. If you don't understand this paragraph then a vernier caliper isn't for you! Overall - a quality tool but for purists. For general use go to HF and get their .001" digital caliper, and some spare batteries. Several reviews here rate that tool better than other inexpensive digital calipers. I gave up and returned this. Expand the photo at the head of this listing. (And you will need an excellent magnifier to see anything like that). Is that showing 0.670" +0.001? +021? +.022? I can't measure with thousandths precision because I can't distinguish which tick is best. I made too many errors compared to using the digital caliper which was unambiguous.

Have purchased dual dial calipers that are near impossible to read. This is easy to read, though a magnifier helps my eyes. The markings are printed well. slide works well enough. good purchase for my needs.

The calipers are spot on with two other digital calipers. I recently had two different digital calipers go bad at the same time. Two very different reasons but they deserve their own reviews. This caliper is meant as a resource in case the replaced digitals fail. I generally use the digital calipers because they are easier but now have a backup to rely on.

La herramienta viene en una caja de plástico junto con unas instrucciones bastante bien hechas, y una regla pequeña recta y un pañuelo para limpiar. Se nota la calidad del material y además, he comparado las medidas con un calibre digital profesional, y la precisión de este es excelente. Muy buen producto

サイズ確認や細かい測定のために購入しましたが、とても使いやすく、目盛りも見やすいです。動きもスムーズで、必要な寸法をしっかり測れました。価格を考えると十分満足できる品質で、家庭用にも作業用にも便利だと思います。買ってよかったです。

Nadat ik mijn twijfels had gekregen over de nauwkeurigheid van de gemiddelde elektronische schuifmaat, weer een ouderwets model aangeschaft. Prima mee te werken, en goed af te lezen. Voelt solide aan, werkt altijd als ik hem nodig heb (geen lege batterij), en afleesbaar tot op 0,02 mm!! Onder de indruk!

In the past, I have spent more on digital callipers which were poorer quality than these. A proper vernier like this one never has flat batteries. There is a pleasing mystique in knowing how to measure accurately to a fraction of a millimetre by reading the vernier scale. These callipers read 0 mm when closed (so they zero correctly) and they move smoothly. They have a reassuring solidity. They come in a reasonably protective plastic case, with a bonus steel rule. Far easier to read than the cheap vernier I've had for many years, and far more reliable than the expensive digital ones I've thrown away. Pleased with my purchase.
